The SP45 4x4 is available with two power options, Diesel-only or Hybrid power:

The Diesel-only option incorporates a versatile and efficient TIER IV compliant engine to deliver maximum traction and gradeability, making it ideal for rough or uneven ground.

The Hybrid option incorporates a smaller, power-optimized TIER IV compliant engine supported by the machine's battery pack for when extra power is needed. This maintains power and performance while reducing fuel consumption for maximum efficiency. The Innovative 'Diesel Re-Gen' feature also recharges the batteries without a mains power source, giving a 'fast-charge' whenever the machine is idle and the engine running. In addition, an electric-only mode allows zero-emission operation, making it ideal for indoor use, or for quiet, clean operation.

Both power options include Niftylift's advanced exhaust purification system, which greatly reduces Carbon Monoxide, Hydrocarbon and particulate emissions making either an environmentally conscious choice.
